The heresy of Bogomilism appeared in the wider region of Thrace, in the mid-10th century. It combined neo-manichean beliefs with the views of Paulician migrants from Asia Minor and of local Slavonic ascetic mouvements. It proposed a dogmatic interpretation but also suggested an essential reformation of the ecclesiastical practice and of everyday life. The Bogomils survived up until the 15th c., despite the persecutions and repeated condamnation of their beliefs by the Church.
